Cambium Savers

[Mark Bolam]

Kram the amount of shite you buy is unreal.

 

Have you ever heard buy cheap buy twice?

 

Just spend your money on proper gear in the first place.

We could've inflated a blimp with the breath we've wasted mate.

Rings from here, tho steel may be over the top. I got them for use as cinching anchors where I didnt want to trust alu but the small is a bit small, and big is too big for that use, so instead have some DMM 34mm alu ones for cinching.

Yes seen the Stein ones, I think their shorter 90cm one will be about double the length I want. The longer it is, the lower your top anchor becomes on a small stem. I assume that any multiple wraps around the stem makes it non retrievable.

 

This At Height lot need a bit of scrutiny. They've sprung up from nowhere, most noteworthily offering a biner that looks a lot like an ISC Big Dan. And I can't for an instant imagine why ISC would be licensing or OEM manufacturing for them. And they've sold kram some bizzare aspartame chrome plated cambium saver ring.

Been using the first two savers quite a lot! I had a birch job recently, I was doing a few hours, every other day, I left the savers up but pulled the ropes through with throwline, they were up nearly two weeks.

 

Inspected them after and noticed some coarse abrasion on the alu rings, no problem on the steel rings. I cant remeber what way around they hung, whether that was from dirty rope abrasion or running on the tree. Marking is not on the inside face of the rings, which makes me think tree. However the abrasion is up and down, makes me think rope.

Rope is soaking in the bath to get any grit and dirt out.

I'll give it a fine polish and rotate the rings so the ropes not touching it. 

 

Any ideas on the cause?

 

Looks like damage from the rings rubbing on each other to me.

Can't help but laugh. The OP is certain he can improve on industry standard kit, for less money, then complains when his own ideas aren't up to his standards.

 

 

Nothing wrong with my splices. It wasnt about saving money but learning and practising the skill of splicing.

 

The rings were bought from HoneyBrothers who are one of the largest UK arb shops, or perhaps one of the most well known. They are rated, 25kN parts from what looks to be a reputable brand.

Have you looked up their history? They were set up by a  ex ISC guy. They are not a traditional manufacturer as they do not make anything themselves.

 

Anyway, I'd suggest chrome is not very well suited to connectors, particually aluminium where the metal underneath is soft. The chrome tends to become rough and flake off.

In this case I believe impact against the tree or between the rings has caused the roughness.

 

Polished them smooth, problem solved, will be using them tomorrow.

 

I have some steel Kong biners that are chromed, so AtHeight are not the only ones. It can flake off of steel too. Its just odd as, annodising is much cheaper, more durable, looks better, doesnt cause any issues when dented or wearing through.

‘Chrome plated, fuel injected and steppin’ out over the line….’

When I still climbed DRT I resigned myself to always returning to the cambium saver in order to retrive it with 100% certainty.

 

That was because I seemed to get it stuck at least half the time which negated any effort saved in installing it in the first place.

 

All in all the most effective cambium saver for me was a steel biner,with a webbing sling and mini pulley on it.Cheap effective and light.

Well they're not really a manufacturer as much as a sourcer/brander then. Which is fine. But reading between the lines it does look like a salesman from ISC looked at one of their products (Big Dan biner, a stalwart) and thought, "I know how many of those they sell and how much they cost to make. I'll get China to make them for less and clean up."

Which is a bit sharp and not the sort of business I'd choose to deal with. Trade with Wales has its own problems but you can at least drive there and shout at them if there's a problem.
